In the release notes, we’ve been told it notes the original iPad will receive Multitasking Gestures when iOS 5.0.1 is available. Currently, these Multitasking Gestures are exclusive to the iPad 2. In earlier betas the original iPad had access to multitasking gestures, however they were not enabled when iOS 5 GM was released.

So, original iPad users, stay tuned for iOS 5.0.1, due to be released in a few weeks.
